The answer is expression (3,-2).
Plug in answer after making a workable expression to y=1+-1x
2x+-3(1+-1x)
2x+-3+3x=-12
5x+-3=-12
-3 -3
5x=-15
x=-3
Plug back to expression
y=1+-3
y=-2
and x already is 3 so that is your answer for that.
Finally!Brainliest if right?
3:2 because they all are dividable by 2
X= 13
y=16
Work:
x+y=29
x=29-y
x+2y=45
29-y+2y=45
y=45-29
y=16
x=29-16
x=13
1/6x = 2.....multiply both sides by the reciprocal 6/1
(6/1)(1/6)x = 2(6/1)
1x or just x = 12
Answer:
the domain of the relation is C
